3 Claims.

My invention relates to improvements in an oil refiner pack casing, and it consists of the combinations; constructions and arrangements hereinafter described and claimed. 1

An object of my invention is to provide an oil refiner pack casing that is an improvement over the casing shown in my co-pending application Serial No. 234,969, filed October 14, 1938. Novel means for providing a tight oil seal between the cover and the casing proper is shown in the copending case. In the present device, I provide the outer surface of thecasing with lugs that are received betweenthe ends of bands that secure the" casing to a support. The lugs Prevent rotation of the casing within the bands when the cover is screwed into closed position or is removed from the casing body.

- Inmy'co-pending device, the oil inlet opening is placed in the cover whereas in my present form, the oil inlet is shown in the casing body 'rather'than in the cover. The'casing may be made in various sizes and I have illustrated two in the drawings. In the larger size, two oil inlets are formed in the sides of the casing and permit an oil inlet pipe to be secured to either side of the casing. The inlet not used is closed by a plug. In the smaller casing, the oil inlet is preferably disposed at the front of the" casing body.

The bottoms of both the small and large cas ings are formed with oil sumps and I have shown two sumps in each casing. The sumps are closed by means of plugs and if desired, the oil inlet pipe may be connected to either sump.

The cover for thecasing body has a plurality of projectionsspaced from each other for receiving a bar or other tool whereby the cover may be rotated into closed or open position. The coverv has a threaded connection with the casing "and a gasket is placed between the parts in'the manner shown in my co-pending application'Serial No. 234,969, now Patent No. 2,249,071, issued July- 15, 1941.

' I provide novel cooperating meansbetween the cover and the oil refiner pack for holding the top; of the'pack against lateral movement. The particular construction of the oil refiner pack forms the subject matter of my co-pending application, Serial No. 312,986, filed January 8, 1940 now Patent No. 2,320,990, issued June 8, 1943. The device is simple in construction and provides an eificient oil refiner for an automobile engine or the like.

, Other objects and advantages will appear in the following specification, and the novel features-of thedevice will be particularly pointed 'out'in the appended claims;

In carrying out my invention, I will first describe the large device and then the small one. I provide a casing body or receptacle A, see Figure' 1,-that is closed by means of a cover B. Lugs I are formed integrally with the outer front face of the-casing and clamping bands 2 extend half way'around the casing body, see Figure 2,-and

have their ends 3 bent outwardly to bear against the opposite sides of the lugs l. The ends 3 of each pair are connected together by bolts 4 and have their other ends 6 connected together by bolts 5. Theends 6 of the bands are bent outwardly at right angles and the ends of each pair are in alignment with each other; The ends 6 are adapted to be attached to a supporting surface, not shown."

The casing body A- has an oiloutlet consisting of a central boss I that extends from both surfaces" of the casingbottom 8. Thisboss rceives the threaded end of an-oil outlet tube 9 that projects from anoil refiner pack H]. The

pack is described in detail and claimed in my co-pending case, Serial No. 312,986, filed January 8, 1940, now Patent No.' 2,320,990, issued June 8, 1943. An oil outlet pipe indicated by the broken line I l communicates with the oil outlet 1 and the pipe carries the refined oil back into a crank case l2 of an engine l3 shown diagrammatically in Figure 1.

An oil inlet opening I4 is provided on each side of the casing body A and near the top thereof. An oil inlet tube [5 may be inserted in either opening l4 and the opening not receiving the tube, is closed by means of a plug l8, see Figure 4. The tube l5 leads to the crank case of the Engine and carries oil from engine tov the oil rener.'

The bottom of the casing has two sumps formed therein and these sumps have drain openings closed by screw plugs l8. The sumps are for the purpose of collecting foreign matter that thicker in order to form a relatively broad rim.

I9. The rim has concentric ribs which form corrugations in a gasket 20. The cover B has a shoulder 2| which is disposed opposite to the rim I9. The shoulder 2| has concentric grooves which are complemental to the ribs and further cause the gasket to be corrugated. The outer edge of the rim I9 is threaded at 22 and receives the threaded interior portion of the cover B.

l The cover has projections 23 spaced from each other, see Figures 1 and5, and a bar or a tool handle may be inserted between the opposed projections for rotating the cover into closed or open position. The projections 23 take the place of the hexagonal central projection shown in my co-pending application Serial No. 234,969, new Patent No. 2,249,071, issued July 15, 1941.

The smaller casing is shown in Figures .51 and and parts corresponding to the larger casing ill be given like reference numerals. The smaller casing A is supported by the bands. ;2 and is held against rotation by the lugs The casing has the outlet opening 1 and the sumps H which are closed by the screw plugs I8.

In place of the .double oil inlet openings I4, I show a single oil inlet opening 25 which is placed at the front of the casing'body A. The

oil inlet pipe l5 shown in Figure 1, communicates with the casing inlet 25 and the oil outlet pipe II, also shown in Figure 1, communicates with the casing outlet v1. The smaller casing body A receives the same cover B as the larger casingA. The smaller casing has the rim I9 with its concentric ridges and the gasket rests on the rim. The cover B has the shoulder 2| with its complemental concentric grooves for corrugating the gasket.

The oil refiner pack |0 carries the oil outlet pipe 9 and this pipe projects beyond the top of the pack as shownat 26 in Figures 1 and 4. The portion is shown wider than the lower portionof the pipe 9 because it is flattened to close the top of the pipe. The flattenedpi-pe portion 26 is received in an annular flange 321 that extends inwardly from the cover B. The flange 21 "forms a cup-shaped recess that has an inner diameter slightly greater than the width of the closed end 26. The flange prevents lateral movement of the top of the pack with-respect to the casing. If the packwere only supported by the pipe connection withthe boss 1, the tendency of the top of thepack to move laterally through the jarring of the automobile, wouldbreak the pipe at the boss.

It is possible tosupport the top end of the pipe in otherways than that shown in Figures 1 and 4. For example, ,in the .modified'form shown in Figure 6, the top of the oil .outlet tubeis left open as at 26a. Thetube is flattened at .28 tolclose this endof thetube andpreventoil from ss,-

- inner surface of the cover.

ing therethrough. The flattened portion 28 has an opening 29 for receiving the key 30 by means of which the pack body is keyed to the core. In all other respects, this type of pack is the sameas that shown in my co-pending application Serial No. 312,986, filed January 8, 1940 now Patent No. 2,320,990, issued June 8, 1943. I

The cover B shown in Figure 6, has a central conical shaped projection 3| for entering the open pipe end 26a. In addition, a plurality of projections 32 are spaced radially from the projection 3| and are circumferentially arranged to bear against the outer surface of the tube end 26a should the tube tend to move laterally and the central projection 3| fail to prevent this movement. The projections 32 also act as spacers between the top Illa of the pack l0 and the The projections 32 coact with the central projection 3| to bear against the inner and outer sides of the tube sim aneouslvte e th p en f e u d support. This dual support for the tube top is necessary since the tube is under constant vi bration when the oil refiner is used on an engine for heavy duty work such as operating a dirt carrying device.

.Still another modified form for securing the top of the pack against lateral movement is shown in Figure 7. In this form, thecentral projection 3| is enclosed in an annular flange .33 corresponding to the flange 21. The open end 26g. of the oil outlettube receives the projection .31 and is held against lateral movementbythe flange 33 should theprojection 3| fail to hold.
